D’Addario Humidipak

The D’Addario Humidipak protects your guitar in two ways. On the one hand, the gel packs release moisture during the dry winter months and protect your guitar from dry damage such as cracks in the top or sticking out frets. On the other hand, they absorb excess moisture during humid periods.

According to D’addario, the Humidipak in the guitar case maintains a constant and optimal climate of 45-50% humidity. So you can free yourself from measuring the humidity and regularly moistening a sponge.
